Description [src]

Sets a fallback function to generate sprites.

It receives the icon name and scale factor, and should return a ShumateVectorSprite, or NULL if the icon could not be generated. It may be called in a different thread, and it may be called multiple times for the same icon name.

If a previous fallback function was set, it will be replaced and any sprites it generated will be cleared.

fallback may be NULL to clear the fallback function.
